Hogwarts: What Mischief Could a Little Snake Get Into?

In a world-crossing adventure through the Harry Potter universe, our protagonist, Crow, finds himself on the streets until Hermione takes him in. Crow then awakens a powerful "Emotion Chest" system! By inciting strong emotions in others, he can unlock treasure chests! Hermione (smiling sweetly): "So, who do you choose—Cassandra or me?" Crow: "Only kids make choices. As an adult... I want them all!" {Silver Chest!} Cassandra (with a haughty expression): "Be mine, and I’ll take care of you!" Crow (blushing): "I'm still an innocent guy, so please be gentle, my dear sponsor!" {Gold Chest!} Crow: "Professor, this cauldron-cooked Scottish chubby chicken is really tasty. Are you sure you don’t want some?" Snape: "You used my potion ingredients to cook chicken? Slytherin, minus ten... no, fifteen points!" {Diamond Chest!} Crow: "Your pet Fawkes keeps hanging around my Azure Phoenix, which has been stressing her out. So... I’ll need compensation for emotional distress!" Dumbledore (dropping a Bertie Bott’s Every Flavor Bean): "Didn’t you ask for that just yesterday?" {King’s Chest!} Crow: "I’m just a little snake hunting for treasure chests—what mischief could I possibly be up to?"
